Southern rail strike: Rail unions urged to stop 'pointless action'
Rail unions involved in the long-running dispute over the role of guards on Southern trains have been urged to stop their "pointless action".
As RMT members continued a 72-hour walkout, which began on New Year's Eve, Govia Thameslink (GTR) said the "door remained open for productive talks".
A spokesman for Southern's parent firm said "the transfer to driver-controlled operation" had almost been completed.
The RMT union said its members remained "rock solid in defence of rail safety".
Many services across the network have been cancelled during the latest three-day walkout with some routes having no trains at all.
Another strike lasting for six days and involving both the RMT and Aslef unions is set to begin on 9 January.
It will involve train drivers from both unions, with most routes not expected to have any services.
The train drivers' union Aslef is continuing with a ban on overtime, adding to the disruption.
